Briggs & Stratton 01938-0, 01815-0 manual From Fuel, To Home Standby

Briggs & Stratton Power Products Home Generator

Installation Manual

•Piping must be of the correct size to maintain the required supply pressures and volume flow under varying generator load conditions with all gas appliances connected to the fuel system turned on and operating.

•Use an approved pipe sealant or joint compound on all threaded fittings to reduce the possibility of leakage.

•Installed piping must be properly purged and leak tested, in accordance with applicable codes and standards.

WARNING

Propane and Natural Gas is extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•Before placing the Home Standby Generator into service, the fuel system lines must be properly purged and leak tested.

•NO leakage is permitted.

Consider the following factors when planning to install the fuel supply system:

The Home Standby Generator engine is fitted with a fuel mixer system that meets the specifications of the California Air Resources Board for “tamper-proof” dual fuel systems. The unit will run on natural gas or liquefied propane.

•A minimum of one accessible, approved manual shutoff valve shall be installed in the fuel supply line within 6 ft (1.8 m) of the Home Standby Generator. A union or flanged connection shall be provided downstream from this valve to permit removal of controls.

•Natural gas fuel supply pressure at the generator's fuel inlet port should be between 5 to 7 inches of water (in. W.C.) at full load. LP fuel supply pressure should be 11 to 14 inches of water (in.W.C.) at full load.

The Home Standby Generator unit has been

factory set to run on natural gas. If you need to change from natural gas to LP gas, the unit will need to be reconfigured, as described on page 13.

It is recommended that the fuel connection incorporate the following components:

•A manual fuel shut-off valve located in the interior of the building.

•A manual fuel shut-off valve located outside the building, just before the generator unit.

•Where the formation of hydrates or ice is known to occur, piping should be protected against freezing.The termination of hard piping should include a sediment trap where condensate is not likely to freeze.

•A manometer port should be provided.

The manometer port permits temporary installation of a manometer (Figure 5), to ensure that the engine receives the correct fuel pressure to operate efficiently throughout its operating range.

Figure 5 — Temporary Manometer Installed

NOTE: A digital manometer, P/N 19495, is available at your local Briggs & Stratton service center.

When the initial test runs are completed, the manometer is removed and the port is plugged. A typical final fuel connection assembly is shown in Figure 6.
